It measures 5 inches in overall length and 20.6 mm in diameter, fitting standard RK5 fuse holders. The dual-element, time delay design allows momentary inrush currents to pass without nuisance opening while still protecting circuits from sustained overloads and short circuits. This fuse is non-indicating and is intended for installation by licensed electricians working on motor branch circuits, HVAC equipment, and other inductive load applications where time delay characteristics are required.\u003c\/p\u003e\n\u003cp\u003eThis fuse is suited for residential and commercial electrical systems where RK5-class overcurrent protection is specified. Common applications include motor control panels, HVAC disconnect boxes, and other equipment requiring a time delay fuse to handle startup inrush currents. It mounts in a standard fuse holder and is appropriate for use in systems where CE, CSA, and UL compliance is required by code or specification.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7.5-amp time delay rating handles inrush current without nuisance tripping\u003c\/li\u003e\n  \u003cli\u003eRK5 fuse class for general purpose branch circuit and motor protection\u003c\/li\u003e\n  \u003cli\u003eDual-element construction provides both overload and short circuit protection\u003c\/li\u003e\n  \u003cli\u003eNon-indicating design in a standard cartridge body\u003c\/li\u003e\n  \u003cli\u003eCE Certified, CSA C22.2 No. 248.12 Certified, and UL Listed 248-12 Class RK5\u003c\/li\u003e\n  \u003cli\u003eMounts in standard RK5-compatible fuse holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an RK5-class replacement fuse for use in standard cartridge fuse holders rated for Class RK5 fuses in branch circuit and motor circuit applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize and lock out the circuit before removing or installing fuses. Verify the fuse holder is rated for RK5-class cartridge fuses and that the amperage rating matches the circuit design. Do not substitute a fuse of a higher amperage rating than what is specified for the circuit.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAmperage\u003c\/strong\u003e: 7.5 amps\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Class\u003c\/strong\u003e: RK5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Type\u003c\/strong\u003e: General Purpose\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Timing\u003c\/strong\u003e: Time Delay\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFuse Body Type\u003c\/strong\u003e: Cartridge\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Elements\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndicating\u003c\/strong\u003e: Non-Indicating\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Fuse Holder\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches (127 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Diameter\u003c\/strong\u003e: 20.6 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CE Certified; CSA C22.2 No. 248.12 Class 1422-02 File 53787 Certified; UL Listed 248-12 Class RK5 Guide JDDZ File E4273\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: COOPER BUSSMANN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FRS-R-7-1\/2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51701225226546,"sku":"FRS-R-7-1\/2","price":176.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bf352439cc30fd3fac604ae784ed1fb4.jpg?v=1788400192","url":"https:\/\/voomisupply.com\/products\/cooper-bussmann-frs-r-7-1-2-rk5-time-delay-fuse-7-5a","provider":"Voomi Supply","version":"1.0","type":"link"}
